Tips for Energy Saving

Avoid	• Do not block the air intake and outlet of the unit. If either is
	obstructed, the unit will not work well, and may be damaged.
	• Do not let direct sunlight into the room. Use sunshades, blinds or curtains.
	If the walls and ceiling of the room are warmed by the sun, it will take
	longer to cool the room.
Do	• Always try to keep the air filter clean. (Refer to “Care and Cleaning.”)
	A clogged filter will impair the performance of the unit.
	• To prevent conditioned air from escaping, keep windows, doors and any
	other openings closed.

NOTE

Should the power fail while the unit is running

If the power supply for this unit is temporarily interrupted the unit will automatically resume operation (once the power is restored) with the same settings that were in effect before the power was interrupted.
